Product details
| Parameter | Value | Remarks |
|---|---|---|
| Standard | ASTM A36/A36M | Standard specification for carbon structural steel by ASTM |
| Grade | ASTM A36 | Commonly used in various structural and construction applications |
| Chemical Composition (wt%) | ||
| – Carbon (C) | ≤0.26 | Influences strength and weldability; controlled to ensure proper balance |
| – Silicon (Si) | ≤0.40 | Aids in deoxidation and impacts the overall properties of the steel |
| – Manganese (Mn) | ≤0.80 – 1.20 | Enhances strength and toughness, crucial for structural integrity |
| – Phosphorus (P) | ≤0.04 | Kept at a low level to avoid brittleness and poor performance |
| – Sulfur (S) | ≤0.05 | Minimized to reduce the risk of cracking during fabrication processes |
| – Copper (Cu) | ≤0.20 | May contribute to improved corrosion resistance to some extent |
| Mechanical Properties | ||
| – Yield Strength (Fy) | ≥250 MPa (≥36 ksi) | Minimum value to ensure the billet can withstand loads without excessive deformation |
| – Tensile Strength (Fu) | 400 – 550 MPa (58 – 80 ksi) | Determines the overall load-bearing capacity in structural applications |
| – Elongation (in 8 in., %) | ≥20 | Provides good ductility for processes like bending, forging, etc. |
| – Bend Test | 180° | Bend diameter: 1.5 times the thickness for specimens ≤ 1.5 in. thick |
| Dimensions | 5 x 5 in (square cross-section) | Nominal size; there are allowable tolerance ranges as per the relevant ASTM standards |
| Length | Customizable according to specific requirements | Usually supplied in certain lengths but can be cut to specific lengths as per customer orders |
| Surface Quality | Generally required to be free from cracks, significant surface defects like deep scratches, and excessive scale | To meet the quality requirements for further processing or application |
| Delivery Condition | Hot rolled, normalized, or as-rolled | Different delivery conditions can be chosen based on specific fabrication needs and usage scenarios |
| Typical Applications | Structural components in buildings, bridges, large industrial frames, heavy-duty storage racks, and other applications where relatively larger sections of structural steel with good strength and workability are needed |
